I'm afraid I have to disagree on the speeds, gents.
LRC is about 5-6% faster (TAS) than the best specific (optimum) range. For this increase you pay about a 1% penalty in range. Max (optimum) range is a very stable speed, only a few knots indicated less than LRC.
Min drag (L/D max, or max endurance) is MUCH slower than max range. It is speed unstable if you get on the back side of it. Generally your holding speeds are 5-10% faster then L/D max to increase speed stability.
Wtih the fuel on board, you can do only two things. Either maximize your hours and minutes until flameout - max endurance. Or, maximize the miles you can fly - max range. Any other speed is a compromize.
The industry has adopted LRC as an acceptable compromize. A 1% penalty for a 5% increase in speed (for schedule) makes sense.
